My immediate thought was definitely the [name]Tempest[/name] reference… don’t do it! I agree that, without the [name]Tempest[/name] connections, it’s a great majestic handsome sounding name. But to anybody who knows their [name]Shakespeare[/name], [name]Caliban[/name] will always be the deformed depraved monster.
To any non Shakespearean readers reading this, here’s a good comparison: it’d be the equivalent of naming your child Gollom.
However, I really like [name]Callahan[/name] as an alternative, and I actually prefer the way it rolls of the tongue. I also like [name]Lachlan[/name].
In short: love the name, hate the connotations, which overrules it for me.
